Description

Novel bulb micrometer

Technical Field

The utility model discloses be applied to measuring instrument's technical field, in particular to novel bulb micrometer.

Background

In linear motion mechanism, the slip table is used for connecting and drives the connecting piece and obtains the removal effect as the moving member. The lower extreme both sides of slip table can be provided with the transverse groove, then install the billet on the transverse groove again, then be provided with the arc wall on the billet for the slip of slip table is spacing. For the distance measurement between the arc-shaped grooves, a common method is to use a micrometer to measure, but the conventional micrometer is difficult to obtain accurate test data for the arc-shaped grooves due to the structural limitation.

Chinese patent CN 204359233U discloses a micrometer with replaceable spherical measuring head, which adopts a structure in which a measuring rod and a measuring ball head are detachable, so that the ball head can be replaced, thereby measuring arc distances of different curvature radii; however, in this patent scheme, the change of bulb needs through tapping the screw hole on the bulb, then through screw hole and measuring stick terminal threaded connection, this has just produced a great deal of inconvenience: the bulb need tap out the screw hole, and the corresponding cost that has increased to the bulb size is less, the shape is slick and sly, snatchs inconveniently, and is very inconvenient when screwing up on the measuring stick, and it is comparatively troublesome to change. Therefore, a novel ball micrometer and a measuring method thereof, which have the advantages of simple structure, low cost and convenient ball replacement, are needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a simple structure, the cost is lower and the bulb changes convenient novel bulb micrometer.

The utility model adopts the technical proposal that: the utility model discloses a blade is in with the setting the measuring stick at blade both ends, two it is equipped with the stop collar all to overlap on the measuring stick, be provided with logical groove in the stop collar, it is provided with the measurement bulb to lead to the inslot, it keeps away from to lead to the groove the one end of measuring stick is provided with the spacing ring, measure the bulb with the spacing ring reaches the measuring stick cooperatees.

Further, the stop collar is in threaded connection with the measuring rod.

Furthermore, ejector rods are arranged on the measuring rods and matched with the measuring ball heads.

The utility model has the advantages that: because the utility model discloses an be in including blade and setting the measuring stick at blade both ends, two all the cover is equipped with the stop collar on the measuring stick, be provided with logical groove in the stop collar, it measures the bulb to lead to the inslot, it keeps away from to lead to the groove the one end of measuring stick is provided with the spacing ring, measure the bulb with the spacing ring reaches the measuring stick cooperatees. Compared with the prior art, the utility model has the advantages of it is following: through adopting the stop collar, the structure that sets up logical groove in addition the spacing ring in the stop collar will measure the bulb restriction, then utilize the measuring stick to push up the measuring bulb on the spacing ring, make the measuring bulb expose, thereby can measure the arc-shaped groove, whole framework is simple, need not measure the bulb and process, and then reduce economic cost, and when needing to be changed, only need to place new measuring bulb on supporting stop collar, again by the stop collar cover can on the measuring stick, the operation is simple, it is convenient to change.

Detailed Description

As shown in fig. 1 to fig. 2, the specific embodiment of the present invention is: the utility model discloses a blade 1 is in with the setting measuring stick 2 at 1 both ends of blade, two it is equipped with stop collar 3 all to overlap on the measuring stick 2, be provided with logical groove 4 in the stop collar 3, it is provided with measurement bulb 5 to lead to groove 4, it keeps away from to lead to groove 4 the one end of measuring stick 2 is provided with spacing ring 6, measure bulb 5 with spacing ring 6 reaches measuring stick 2 cooperatees. The ruler body 1 is a conventional part, the limiting sleeve 3 is matched with the measuring rod 2, the through groove 4 is used for placing the measuring ball head 5, the limiting ring 6 is matched with the measuring rod 2, the position of the measuring ball head 5 can be limited, the measuring ball head 5 is prevented from falling off, and meanwhile, the measuring ball head 5 can be partially exposed to measure an arc-shaped groove to be measured. By the above, the utility model has the advantages that the whole structure is simple, through measuring stick 2 with stop collar 3 reaches spacing ring 6 can with measure bulb 5 restriction in fixed position, thereby it is right not need to measure bulb 5 and process, be favorable to reducing the processing cost, simultaneously, at the in-process of changing the installation, only need place new measurement bulb in the stop collar of adaptation, again the stop collar cover is in can accomplish the change on the measuring stick 2, easy operation, it is convenient to change.

In this embodiment, the stop sleeve 3 is screwed to the measuring rod 2. The matching mode of threaded connection is adopted, so that the connection between the limiting sleeve 3 and the measuring rod 2 is more stable, a better connection effect is obtained, the conditions of looseness and the like cannot occur easily, and the measuring accuracy is guaranteed.

In this embodiment, the measuring rod 2 is provided with a top rod 7, and the top rod 7 is matched with the measuring ball 5. The diameter of the ejector rod 7 is smaller than that of the measuring rod 2, and the ejector rod is used for tightly ejecting the measuring ball head 5, so that the ejector rod can be tightly attached to the limiting ring 6, can extend into the through groove with the smaller diameter, and is suitable for more limiting sleeves with different sizes.

The utility model discloses a theory of operation is:

before measurement, the measuring ball head 5 and the limiting sleeve 3 which are matched with each other are prepared in advance, then one end, provided with the limiting ring 6, of the limiting sleeve 3 faces downwards, and the measuring ball head 5 is placed in the through groove 4; sleeving the limiting sleeve 3 on the measuring rod 2 and screwing the limiting sleeve, wherein the ejector rod 7 props against the measuring ball head 5, so that the measuring ball head 5 is exposed; during measurement, the two exposed measuring ball heads 5 are respectively aligned to the arc-shaped groove to be measured, and then the fine tuning screw of the micrometer is rotated to enable the two measuring ball heads 5 to be tightly attached to the arc-shaped groove to be measured, so that the measurement is completed; when arc-shaped grooves with different sizes need to be measured, the limiting sleeve 3 and the measuring ball head 5 are taken down, and then the new limiting sleeve 3 and the measuring ball head 5 with proper sizes are replaced.

While the embodiments of the present invention have been described in terms of practical embodiments, they are not intended to limit the scope of the invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
